Book excerpt: Excerpt from Geologic Map and Report for the Theodore Roosevelt Dam Area, Gila and Maricopa Counties, Arizona All three units are exposed near the southeast abutment of Theodore Roosevelt dam where a 30-m-deep channel has been incised into Troy Quartzite, Mescal Limestone, and basalt associated with the Mescal Limestone. The channel fill includes a lower ferruginous sandstone and an overlying, very poorly sorted feldspathic sandstone (see detail map, Figure We have assigned the lower unit to the Bolsa Quartzite. It is typically ferruginous in its lower part, but variably bleached in the upper part with locally striking Liesegang banding. Sand is moderately sorted, feldspar is not a prominent constituent, but in some places magnetite is common. Troughy cross beds are abundant.
